Re: [osg-users] Showing and hiding objects by removing/adding drawables.

Hi Jesper, Adding/removing node/drawables/stateset from the scene graph is not something I would recommend users do for toggling the visibility of items. The best way is to decorate the subraphs with an osg::Switch node, or use the osg::Node::set/getNodeMask(uint) setting it to 0x0 and

Re: [osg-users] Showing and hiding objects by removing/adding drawables.

The event picker doesn't take a nodemask to traverse like the nodevisitor, so it returns all hits - visible or not. I made a small mod to the IntersectorVisitor to take a traversal mask and only visit those nodes with it set. It needs a bit of cleaning up to meet OSG standards - I will post it

Re: [osg-users] Showing and hiding objects by removing/adding drawables.

But there didn't seem to be any code inside the intersector to act on the traversal mask. I added to: Code: bool IntersectorGroup::enter(const osg::Node node) { if ( !(node.getNodeMask() _traversalMask) ) return false; . Martin -- Read this topic online here:

Re: [osg-users] Showing and hiding objects by removing/adding drawables.

Hello Martin, But there didn't seem to be any code inside the intersector to act on the traversal mask. Again, since IntersectionVisitor is a NodeVisitor, the traversal will implicitly call NodeVisitor::traverse(node), which calls either Node::ascend(nv) or Node::traverse(nv), which for
